public abstract class TimeContext
This class represents a test context
specialized
for measuring execution time.
TimeContext
implementations may perform assertions based upon the
execution time. For example:
class MyTestCase extends TestCase() {
...
protected void validate() {
long ns = TimeContext.getAverageTime("ns");
TestContext.assertTrue(ns < 100); // Error if execution time is more than 100 ns.
...
}
}
Field Summary | |
---|---|
static Configurable<java.lang.Class<? extends TimeContext>> |
DEFAULT
Holds the time context default implementation (by default logs average and minimum execution time to System.out ). |
static java.lang.Class<? extends TimeContext> |
REGRESSION
Holds an implementation which does not perform any logging but raises an AssertionException when an assertion fails, including any timing
assertion. |
static Configurable<java.lang.Integer> |
TEST_DURATION_MS
Holds the minimum duration of each test execution (default 1000 ms). |
